Add a device node for the System Controller, with subnodes that
represent the hardware power area hierarchy.
Hook up all devices to their respective PM domains.
Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
---
This depends on "[PATCH] ARM: hw_breakpoint: Trap undef instruction
exceptions on wake-up", or an alternative solution. Else resuming from
s2ram will cause a crash.
As the HDMI-Link device is not yet instantiated from DT, this does not
depend on "[PATCH/RFC] fbdev: sh_mobile_hdmi: Re-init regs before irq
re-enable on resume".
v3:
- Move power-on/off latencies to a separate patch,
- Add dependencies,
v2:
- Insert power-domains property after clock-names property in the cmt1
node.
